摘要

自进化论诞生以来,拟态就为适应性峰值移动、物种分化、表型多态性的出现和维持等基础性进化过程提供了洞察力。尽管对鳞翅目系统中贝茨拟态和缪勒拟态的理解取得了重大进展,但很少有其他拟态系统得到类似的详细研究。在这里,我们展示了一个贝茨拟态复合体,包括不会飞的、有甲的Pachyrhynchus象鼻虫及其有翅的Doliops长角甲虫拟态体,并研究了它们在菲律宾群岛内的共同进化模式。Pachyrhynchus象鼻虫主要分布在菲律宾,不同的岛屿上出现了不同的物种辐射,每种象鼻虫都有独特的颜色图案,对捕食者起到警告作用。华莱士于 1889 年首次描述了这种防御特性以及不相关物种之间的拟态。值得注意的是,远亲长角甲虫 Doliops 尽管身体柔软,表面上可食用,但却模仿重甲、不会飞的 Pachyrhynchus。为了解决这一系统中的模仿问题,我们利用由 38,000 个超保守元素组成的探针集重建了 Doliops 的系统发育。我们的研究探讨了以下对于理解 Pachyrhynchus-Doliops 拟态系统至关重要的问题:(1)共同进化的相互作用在多大程度上是保守的(即世系受限);(2)编码多样化模式主要是由生物因素还是非生物因素驱动的?我们的研究结果表明,甲虫有能力针对类似的进化挑战反复演化出多种解决方案,利用不同类型的光子晶体以不同的有序程度演化出类似的颜色模式。我们发现,观察到的共生模式主要是由其生物地理历史中的非生物因素驱动的。与被子植物和昆虫种系之间的共同进化模式不同7,大多数生态相互作用的持续时间不会超过几百万年,这导致了模块化模式而非生态嵌套模式。

Biogeography confounds the signal of cospeciation in Batesian mimicry.

Since the inception of the field of evolution, mimicry has yielded insights into foundational evolutionary processes, including adaptive peak shifts, speciation, and the emergence and maintenance of phenotypic polymorphisms.1,2,3 In recent years, the coevolutionary processes generating mimicry have gained increasing attention from researchers. Despite significant advances in understanding Batesian and Müllerian mimicry in Lepidopteran systems, few other mimetic systems have received similar detailed research. Here, we present a Batesian mimicry complex involving flightless, armored Pachyrhynchus weevils and their winged Doliops longhorn beetle mimics and examine their coevolutionary patterns within the Philippine archipelagos. Pachyrhynchus weevils are primarily found in the Philippines, where distinct species radiations have occurred on different islands, each with unique color patterns serving as a warning to predators. This defensive trait and mimicry between unrelated species were first described by Wallace in 1889. Notably, the distantly related longhorn beetle Doliops, despite being soft-bodied and ostensibly palatable, mimics the heavily armored, flightless Pachyrhynchus. To address mimicry in this system, we reconstructed the phylogeny of Doliops using a probe set consisting of 38,000 ultraconserved elements. Our study examines the following questions central to understanding the Pachyrhynchus-Doliops mimicry system: (1) to what extent are coevolutionary interactions conserved (i.e., lineage-constrained) and (2) are the codiversification patterns primarily driven by biotic or abiotic factors?4,5,6 To assess color mimicry and cospeciation, we examined the evolution of nanostructure-based warning colors and the effect of island biogeography on cospeciation. Our findings demonstrate the beetle's ability to repeatedly evolve multiple solutions to similar evolutionary challenges, evolving similar color patterns using different types of photonic crystals with varying degrees of order. We revealed that the observed pattern of cospeciation is driven mainly by abiotic factors from their biogeographic history. Unlike the patterns of coevolution seen between angiosperms and insect lineages,7 most ecological interactions do not persist longer than a few million years, leading to patterns of modularity rather than ecological nestedness.4,6,7.
